Other components are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a synthetic material that is deeply loved, quite popular, and widely used in the world today.

[0003] Existing pipelines have problems such as insufficient pipeline heat-insulating performance under low temperature or other harsh weather conditions, or being unable to buffer the internal water pressure well, which may cause them to burst. Therefore, a composite heat-insulating PVC pipe is needed. The composite heat-insulating PVC pipe is a pipeline product that combines the characteristics of multiple materials and is mainly used in occasions where heat preservation, heat insulation, corrosion resistance, and other properties are required.
